This role-play is performed by adults. I have a girl who has been my childhood friend since I was little. There is no such thing as shame between men and women because they have been together for too long! On a hot summer day, my childhood friend brings a female friend along and takes off her school uniform as usual, saying, ``Let's cool off a bit,'' and forcibly tears off her female friend's uniform, saying, ``I'm used to seeing this guy!'' As expected, I can't stand girls other than my childhood friends in their underwear, so I get a full erection! I thought they would be drawn to it...but the two girls also turned on their erotic switches and before we knew it, we had a threesome while sweating!
